April 16, 2013 — Researchers are developing a novel technology that would facilitate close monitoring of bridges, parking decks and other structures for early signs of strain, stress and formation of cracks. Their approach uses wireless sensors that are low cost, require no power, and can be implemented on tough yet flexible polymer substrates.

March 29, 2013 — A research team has developed an ultra-compact passive true time delay device that could help reduce the size, complexity, power requirements and cost of phased array designs. The patent-pending device takes advantage of the difference in speed between light and sound to create nanosecond signal delays needed for beam steering.
March 18, 2013 — A team of researchers at the Georgia Institute of Technology has developed a new type of interface between cochlear implant devices and the brain that could dramatically improve the sound quality of the next generation of implants. Cochlear implants help deaf individuals perceive sound.
March 18, 2013 — ECE Assistant Professor Azad Naeemi has received a National Science Foundation CAREER Award for his research project entitled "Physical Models and Experimental Validation for High-Frequency Multilayer Graphene Interconnects."
March 1, 2013 — The Office of Industry Engagement — part of the Georgia Tech Research Corporation (GTRC) — has developed four contract mechanisms that enable industry to engage with Georgia Tech researchers at all stages of R&D.
February 27, 2013 — Researchers have demonstrated the use of a technique known as small angle neutron scattering (SANS) to study the effects of ions moving into nanoscale pores. The study is believed to be the first application of the SANS technique for studying ion surface adsorption in-situ.
February 21, 2013 — A new study provides details of the structure and tissue properties of the unique adhesion system used by remora fish to attach themselves to sharks and other marine animals. The information could lead to a new engineered reversible adhesive that could be used to create pain- and residue-free bandages, attach sensors to objects in aquatic or military reconnaissance environments, replace surgical clamps and help robots climb.
February 4, 2013 — Agilent Technologies Inc. (NYSE: A) today announced the largest in-kind software donation ever in its longstanding relationship with the Georgia Institute of Technology.
January 16, 2013 — A research team at the Georgia Tech Research Institute (GTRI) is developing an airborne testing capability for sensors, communications devices and other airborne payloads. This aerial test bed, called the GTRI Airborne Unmanned Sensor System (GAUSS), is based on an unmanned aerial vehicle (UAV) made by Griffon Aerospace and modified by GTRI.
January 16, 2013 — Farrokh Ayazi, a professor in the School of Electrical and Computer Engineering, is among the 298 individuals worldwide named as a 2013 IEEE Fellow.

December 10, 2012 — Researchers are creating graphene p-n junctions by transferring films of the electronic material to substrates that have been patterned by compounds that are either strong electron donors or electron acceptors.
November 18, 2012 — By fabricating graphene structures atop nanometer-scale “steps” etched into silicon carbide, researchers have for the first time created a substantial electronic bandgap in the material suitable for room-temperature electronics. Use of nanoscale topography to control the properties of graphene could facilitate fabrication of transistors and other devices, potentially opening the door for developing all-carbon integrated circuits.

October 11, 2012 — Understanding the phenomenon of blackbody radiation – electromagnetic emissions that play a role in a broad range of physical systems – is an important part of physics instruction at both the high school and college levels. Thanks to researchers at the Georgia Tech Research Institute (GTRI), explaining this to students just became a little easier.
August 21, 2012 — Researchers have developed a self-charging power cell that directly converts mechanical energy to chemical energy, storing the power until it is released as electrical current. The development avoids converting mechanical energy to electrical energy for charging a battery.
July 29, 2012 — Plastic electronics hold the promise of cheap, mass-produced devices. But plastic semiconductors have an important flaw: the electronic current is influenced by “charge traps” in the material. New research reveals a common mechanism underlying these traps and provides a theoretical framework to design trap-free plastic electronics.
July 10, 2012 — Researchers have discovered yet another way to harvest small amounts of electricity from motion in the world around us – this time by capturing the electrical charge produced when two different kinds of plastic materials rub against one another. Based on flexible polymer materials, this “triboelectric” generator could provide alternating current (AC) from activities such as walking.
